Groundwater accounts for nearly 40% of California’s water supply

• Mono Lake Decision - 1994 – Reduced Los Angeles Aqueduct Supply • Quantification Settlement Agreement - 2003 – Reduced Colorado River Aqueduct Supply • Chinook and Delta Smelt Protections - ongoing – Reduced State Water Project and CVP Supplies

 Completed 1945 by USBR  Dam height – 602 feet  Storage capacity – 4.55 MAF  Maximum flood space – 1.3 MAF  Surface at full pool – 29,500 ac  Generating capacity – 710 MW

• Executive Order B-21-13: Streamline water transfers (May 2013) • California Water Plan Update (draft Oct 2013) • Drought Task Force Established (Dec 2013) • Governor’s Drought Proclamation and Water Action Plan (Jan 2014)

• Water is California’s Life Blood • California’s Complex Water Resources System is in Crisis • A Diverse Portfolio Approach is Required • The Solution Requires Integration, Alignment and Investment • We All Have a Role to Play in Securing Our Future

1. Make conservation a California way of life 2. Increase regional self-reliance and integrated water management across all levels of government 3. Achieve the co-equal goals for the Delta 4. Protect and restore important ecosystems 5. Manage and prepare for dry periods 6. Expand water storage capacity and improve groundwater management 7. Provide safe water for all communities 8. Increase flood protection 9. .Increase opera1onal and regulatory efficiency 10. Identify sustainable and integrated financing opportunities

• State – made $6??M available for water project development • Federal – made $300 M available for aid and water projects – Introducing legislation to authorize 4 storage projects

• Prior Appropriation – Origin in 1880’s from Miner’s Claims – “First in Time, First in Right” – Junior and Senior Rights – Permitted and Non-Permitted Appropriations – Beneficial Uses

Existing Water Supplies Projected Water Demand Surplus (+) or Need (-)  Project future population and water demand  Quantify existing and future water supplies  Identify surpluses and needs  Evaluate and recommend water management strategies  Make policy recommendations  Adopt the plan

• Acquire feasible reservoir sites • Address Inter-basin transfer issues • Desired future conditions petition process • Water loss audits • Finance the State Water Plan

• Reliability is best achieved through diversification • Conservation and reuse are fundamental elements • Planning is important but IMPLEMENTATION of the plan is critical • Energy water demand needs to be considered • Funding is never enough
